The relationship between depression symptoms and cortisol levels in adolescents: the role of somatic symptoms and cognitive function
To examine the associations between plasma cortisol levels and depressive severity, cognitive function, and somatic symptoms in adolescents with depression.
Approach:
Study Design: Cross-sectional study involving 138 adolescents categorized into three groups based on depression severity and somatic symptoms.
Data Analysis: Utilized general linear model (GLM) and simple slope analysis to assess the interactions between clinical variables and cortisol levels.
Key Findings:
No direct associations between cortisol levels and clinical indicators were found in bivariate correlations.
Significant interaction effects were identified: PHQ−15 × HAMD−24 and PHQ−15 × MoCA.
Higher somatic symptoms were associated with lower cortisol levels only under conditions of low-to-moderate depression and low cognitive function.
Interpretation:
The association between somatic symptoms and cortisol in adolescents is moderated by depression severity and cognitive function.
Limitations:
The study is cross-sectional, limiting causal inferences.
Sample size may not be sufficient for generalization.
Conclusion:
The findings indicate a complex interaction between somatic symptoms, cognitive function, and cortisol levels in adolescents with depression.
